Description of problem: during F15a i386 DVD boot after loading initrd.img the boot process stops at 10.4xxxxx [<c040377e>] kernel_thread_helper +0x6/0x10 (line number varies i.e.: 10.455187, 10.466780, 10.470995) Version-Release number of selected component (if applicable): Fedora 15 alpha i386 DVD How reproducible: every time attempt to boot from DVD Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: Chipset: SIS735 Board: ECS K7S5A CPU: AMD Duron 1100 RAM: 512 MB Video: AGP ATI GC-R7000L-B3 Radeon-7000 (RV100) (DVD download passed SHA256 checksum)
The varying number is a timestamp. The line "[<c040377e>] kernel_thread_helper +0x6/0x10" is a part of a kernel stack trace. It is the least informative part of it though. Could you please capture the complete trace (say, using a digita camera)? There's no indication why systemd should be blamed. I'll reassign to kernel for now.
You need at least 1GB of memory to boot the install disk.
Not sure why fedora suddenly started needing 1GB RAM just to boot into Anaconda in GUI or Text interface. It used to work even with 256 MB RAM till F14

How reproducible: every time attempt to boot from CD Steps to Reproduce: 1. Boot Fedora 15 beta netinst CD into Qemu with 512 MB RAM 2. See the oops messages (screenshot already attached) 3. Actual results: System hangs Expected results: Anaconda installer needs to run
(In reply to comment #3) > Not sure why fedora suddenly started needing 1GB RAM just to boot into Anaconda > in GUI or Text interface. It used to work even with 256 MB RAM till F14 The trace shows it failed at unpacking the initramfs. It's likely because of the much bigger initramfs in F15 (http://fedoraproject.org/wiki/Anaconda/Features/UnifiedInitrd) The release notes say: Recommended RAM for graphical: 512 MiB http://docs.fedoraproject.org/en-US/Fedora/15/html/Release_Notes/sect-Release_Notes-Welcome_to_Fedora_15.html#sect-Release_Notes-Hardware_Overview It's unfortunate that 512 MiB is not enough anymore, because that's what virt-manager gives you by default for a new VM. Either anaconda should be fixed to require less RAM, or at least the release notes must be updated to state the true requirements.
